I. FIELD OF THE INVENTION

The present invention in at least one embodiment provides a system and method for monitoring and storing one or more biomedical readings of an individual along with a correlated temporally-based, geospatial location data such that known health issues and diseases associated with the geospatial locations visited by the individual can be used to assist medical professionals with diagnosis of the individual.

II. BACKGROUND OF THE INVENTION

Modern medical professionals have to contend with illnesses from all over the world. Due to the speed and accessibility of international travel, the spread of disease can be very fast and prolific. When performing a diagnosis, medical doctors often take into account diseases that they are familiar with and the diseases that they believe to be common, e.g., to the presenting symptoms. This information can be sufficient to correctly diagnose a patient, however this does not hold true for all cases. For example, doctors may be unaware of a known illness or outbreak in a distant location recently traveled to by a patient, which may result in a misdiagnosis that could have been easily made given the knowledge of the illness or outbreak. Further, doctors are known to be influenced by recent cases that they have seen and consequently more rare or atypical illnesses with similar symptoms to a common, recently observed case presents a heightened possibility for misdiagnosis.

V. DETAILED DESCRIPTION OF THE DRAWINGS

The present invention in at least one embodiment provides a system and method for real-time monitoring, tracking, and storing of information related to the biomedical condition and health characteristics of an individual with respect to date, time, and geographic location such that the causes and/or sources of illnesses and/or diseases can be more efficiently and reliably determined by medical professionals. In at least one embodiment, the present invention allows the stored biomedical data of the individual to be used with or mapped to known health issues and/or diseases associated with the geographic locations visited by the individual. The stored biomedical data provides medical professionals with a full and clear representation of the biomedical history of the individual along with temporally related geospatial information such that known health issues and illnesses of particular locations can be quickly and reliably identified.

The present invention in at least one embodiment provides a medical diagnosis system and method that monitors and stores biomedical readings of an individual with respect to date, time, and geographic location. The present invention in at least one embodiment enables the improved diagnosis of illnesses and/or diseases to be made based on the logged health characteristics of the individual and the known health issues and diseases associated with the geographic locations visited by the individual. In at least one further embodiment, the stored data can provide relevant information to medical professionals when the individual is unable to communication, for example, when he/she is unconscious or speaks a different language.

FIG. 1 illustrates an example of a system in accordance with an embodiment of the present invention for monitoring and gathering the biomedical condition of an individual with respect to the temporal geospatial location data for the individual. The illustrated example includes a device 110 in communication with one or more biomedical sensors 150. The device 110 includes a location module 112, a communications module 114, a memory (or storage) 116 that in at least one embodiment includes a database, and a monitoring module 118. Examples of the device 110 include mobile phones, smart phones, personal digital assistants (PDAs), cameras, electronic book readers, tablet computers, netbooks, laptops, mp3 or other music players, global positioning system (GPS) devices, application specific devices, and the like that include computing capability such as a processor programmed to run the modules.

The location module 112 receives signals from the communications module 114 for use in determining location. Examples of these types of signals include GPS satellite signals, signals from nearby cellular telephone towers, and radio frequency identification (RFID) (or similar type) signal data identifying location. In an embodiment that uses signals from GPS satellites and cellular telephone towers, those signals are processed by the location module 112 to identify the location where the device 110 is located based on relative signal strength received from at least two signal emitters. In an embodiment that uses the RFID signal or similar signal having that information, the signal itself will include information identifying the geographic location in which the device 110 is or passes through. An example of this type of signal is that a signal source present at a checkpoint identifying the city where the checkpoint is located. A further possible source of geospatial data is from a WLAN signal including identification information as to the location of a hub or router such as at a hotspot location where the IP address is converted into a geographical location of the hub/router. The location module 112 stores the geospatial location information into the memory 116 to be associated with biomedical readings.

The communications module 114 is preferably capable of supporting a variety of communications platforms and protocols such as wireless protocols, Bluetooth or other infrared short range wireless communication, Short Message Service (SMS) messaging, Multimedia Messaging Service (MMS), Global System for Mobile (GSM) communications standard, the Code Division Multiple Access (CDMA) communication, Global Positioning System (GPS), Worldwide Interoperability for Microwave Access (WiMAX), wireless local area networks, wire network connection, etc. The communications module 114 in at least one GPS embodiment is capable of communicating on one or more GPS communication platforms such as the United States NAVSTAR system, the Chinese Compass system, the French Galileo system, the Russian GLONASS system, and other similar systems. The communications module 114 also provides the connection to the sensors 150 associated with the individual being monitored. Examples of the connections to the sensors 150 include wireless and wired. The wireless connections in at least one embodiment would use existing protocols to establish the connection between the device 110 and the sensor 150. Alternatively, the sensor 150 could be connected to the device 110 with a cable or other wire. In a further embodiment, the device 110 may include a built-in sensor 150. In a still further embodiment, the data produced by the sensor 150 is read from a memory card or entered into the device 110 using, for example, the screen and/or keypad/keyboard on the device 110.

As illustrated, the device 110 further includes a monitoring module 118 in communication with the communications module 114. The communications module 114 provides the biomedical signals from the one or more sensors 150 to the monitoring module 118 for processing and interpretation of what the signal represents. In at least one embodiment, the communications module 114 also provides identification of the source of the biomedical signal to aid in interpreting the signal by the monitoring module 118. The data obtained from the signal is provided to the memory 116 for storage with a time-stamp representing the time the biomedical reading was obtained.

In at least one embodiment, the monitoring module 118 pings one or more sensors 150 in communication with the device 110 to provide the current biomedical reading of the sensor 150 for storage in the memory 116. In this embodiment as illustrated in FIG. 2, the monitoring module 118 is in communication with a clock 220 and/or timer to provide a time signal to be used in determining whether a predetermined time has passed and at least one new biomedical reading is to be obtained from one or more sensors 150. In a further embodiment, the monitoring module 118 sets a predetermined time period between readings for each sensor 150 where the time periods may be the same for all sensors, the same for some sensors and different for at least one other sensor, or different for each of the sensors in communication with the communications module 114. The predetermined time periods may be stored in memory 116 for retrieval by the monitoring module 118. Once the predetermined time has been reached, the monitoring module 118 has the communications module 114 ping the relevant sensor(s) 150 for a reading(s). In at least one embodiment where the sensor 150 is built into the device 110 or the sensor 150 requires the individual to provide the reading, the monitoring module 118 provides an alert or other notification to the user that a reading is needed. Examples of an alert/notification include an audio queue like a beep, bell, or music through a speaker; a tactical queue like vibration of the device 110; a visual queue like a light; or some combination of these different queues.

In a still further embodiment, at least one predetermined time period is shorten when the reading from the associated sensor 150 changes in excess of a predetermined change for the particular sensor stored in the memory 116. An example of the predetermined change using temperature is a percentage change in temperature or a fixed amount such as two degrees over a period of time or between the two most recent temperature readings.

In another embodiment, the monitoring module 118 determines whether the most recent biomedical reading is substantially similar to the previous reading such that it can be omitted from being stored in memory 116 and that upon retrieval of the stored data the device 110 will insert the reading from the previous reading in time into any display or transfer of the information.

In at least one further embodiment, the monitoring module 118 is integrally incorporated into the communications module 114.

The memory (or storage) 116 is in communication with the location module 112 and the monitoring module 118 for storing the data produced by these two modules. In at least one embodiment, the data is stored in a database residing in the memory 116. The memory 116 provides storage of any predetermined time periods or changes used by the monitoring module 118 for those relevant embodiments. The temporally based information related to the biomedical reading(s) and geospatial location of the individual allows medical professionals to quickly and reliably access and use the information at a later time. This stored information greatly enhances the ability of medical professional to accurately diagnose illness and disease related to the individual by providing a full and clear temporal representation of the recent travel and health of the individual.

Once the stored information related to the recent travel and health of the individual is accessed, this information can be correlated with other information to assist with diagnosis. The correlation of the information can be done, for example, by a programmed external computer in embodiments where the data is transferred from the device 110 or by the communications module 114 (or a separate search module connected to the communications module 114 and the memory 116). Other sources of information (or supplemental data), such as health organization reports, may also be used including known illnesses, diseases, and health issues in the areas traveled to by the individual. In embodiments where the device 110 performs the search, the supplemental data may be stored in memory 116 and correlated to the geospatial location data. These reporting sources may include various entities that adhere to proscribed standards of reliability such as private medical facilities, e.g., hospitals and clinics, governmental organizations, e.g., the Centers for Disease Control and Prevention (CDC), and the World Health Organization (WHO), etc. The information obtained through these reporting sources may include, for example, current epidemic alerts, the scale of each active epidemic based on a standard, e.g., the phase level number, per location around the world, and the number of affected people reported. The alerts could be archived by the medical professional and searched using the geospatial information associated with the patient.

FIG. 3 illustrates a further embodiment according to the invention. The illustrated embodiment adds a display 330 and an interface engine 332 to the embodiment illustrated in FIG. 1. The interface engine 332 pulls data from the memory 116 to display data on the display 330. Examples of how the data may be displayed are discussed later in connection with FIGS. 9 and 10. The interface engine 332 retrieves the data from the memory 116 that includes, for example, biomedical readings, geospatial location data, and temporal information for the biomedical readings. In at least one further embodiment, the interface engine 332 also provides any supplemental data that is located during a search performed by the communications module 114.

At least one of the sensors 150 is a biomedical sensor(s) that monitors one or more physiological conditions, e.g., body temperature, sugar levels, breathing rate, pulse rate, heart rate, blood oxygenation, level of activity, blood pressure, etc. The sensors 150 may be, for example, non-invasively attached to the body or located in clothing of the individual and in communication with the device 110. In a further embodiment, at least one sensor 150 is implanted in the individual. In a still further embodiment, the sensor 150 is incorporated into the device 110. The communications module 114 of the device 110 is programmed to receive signals from the sensors 150 representative of at least one physiological condition to obtain a biomedical reading. The communications module 114 provides the signal to the monitoring module 118 for processing. The device 110 stores the received signals such that the temporal health of the individual can be determined later based on the stored information.

The sensors 150 for use as part of the system can take a variety of forms. Examples of biomedical sensors include: heart rate (or pulse) sensors, respiration sensors, oximeters, thermometers, blood glucose monitors, blood pressure cuff systems, actigraphs, and any combination of these sensors. One or more of these sensors could be built into the device 110 to have the individual grasp or place a thumb/finger on the sensor to detect, for example, pulse rate or temperature. The sensors also could be non-invasive and incorporated into clothing, placed on straps, or incorporated into wrist bands worn by the individual. In at least one embodiment, the sensor is incorporated into medical equipment used by the individual such as a Continuous Positive Airway Pressure (CPAP) machine or a pacemaker.

In an alternative embodiment, the device 110 is replaced with a card 410 having a memory (or storage) 416 and a communications module 414 as illustrated in FIG. 4. In this embodiment, the card 410 will obtain location information from wireless transmitters or data readers/writers 490 that identify the location such as a RFID transmitter located at a passport control booth, a RFID transmitter at a toll booth or subway station, a card reader/writer at a passport control booth that is able to write to the card, etc. The sensors 150 in such a system would provide their respective readings wirelessly for storage on the card 410 to enable the data to be read (or transmitted) and correlated with temporal data and the respective geospatial data. In this embodiment, the sensors would have additional processing responsibility to provide the data in the appropriate form for storage on the card 410. The communications module 414 in this embodiment is a RFID (or other wireless) transmitter/receiver or a magnetic medium such as a magnetic strip built into the card 410. In a further embodiment, the card 410 would include a power supply 522 as illustrated in FIG. 5.

FIG. 6 illustrates an example of a method in accordance with at least one embodiment of the present invention for monitoring and tracking the biomedical condition of an individual with respect to temporal geospatial location. The device 110, 410 is prompted to begin monitoring and storing geospatial and biomedical information (610).

The device 110, 410 monitors (620) and stores (630) the geospatial position of the device using, for example, GPS location, location determined based on proximity to cellular (or other wireless) towers (or access points), and entry and departure through identification check points such as passport (or border) control. Additional discussion of how the geospatial data and geographic location is obtained is discussed above in connection with the device and card embodiments.

At predetermined time periods (or continuously depending on the parameter being measured), the device 110, 410 receives (or obtains) at least one biomedical signal (640) and stores at least one biomedical reading (or parameter) of the individual (650) based on the signal from one or more biomedical sensors 150 associated with the device 110, 410 as discussed above. The sampling rate in a further embodiment is set and/or adjusted based on the advice of one or more medical professionals. In at least one embodiment, the device 110 pings the at least one biomedical sensor to provide the current reading of the parameter it is measuring. The timing of the monitoring can be at predetermined intervals such as hourly, every few hours, daily, weekly, etc. The timing can vary between biomedical readings being monitored by the device 110, for example, the temperature may be recorded every six hours while blood pressure is measured daily. In at least one embodiment, the frequency of monitoring of a biomedical reading changes if the change between the two most readings is in excess of a predetermined threshold. In at least one embodiment, the trigger for pinging the at least one biomedical sensor 150 is based on a change in geographic location such as entering/leaving a population center, city, or country. In at least one embodiment, the device 110 stores the biomedical data only when it is different from the previous reading, for example, when it changes or changes in excess of a predetermined threshold for the biomedical parameter being measured resulting in reduced storage requirements in the device from a reduction in data. The biomedical data is associated with the geospatial data.

Each entry of data, in at least one embodiment, is time stamped by the device. The time used could, for example, be the local time of where the individual is located, the time of where the individual lives, or a standard time such as Greenwich Mean Time. The monitoring of biomedical parameters and time stamping are repeated based on the timing of the biomedical parameter monitoring. The determination of geographic location can occur, for example, in conjunction with the biomedical reading monitoring, be continuously checked, be checked at predetermined times, or done on an ad hoc basis such as manual entry of the data or manual request by the individual.

FIG. 7 illustrates an example of a method in accordance with an embodiment of the present invention for diagnosing the cause of the illness and/or the disease. An individual making use of an embodiment described above feels ill seeks the care of a medical professional.

The medical professional is granted access to the stored biomedical data and geospatial location information related to the individual (710) and performs an analysis of the stored information in an effort to determine the location of infection. The medical professional is granted access to the stored biomedical and geospatial location data through, for example, the device 110 used by the individual or by downloading the information from the device 110 or the card 410 to a computer for reviewing the information.

The medical professional checks (or searches) reports of known illnesses and diseases (or supplemental data) provided by health organizations and other trusted sources (720). The checking of the report in at least one embodiment the medical professional causes a search to be done using the geospatial location data to select the relevant alerts and further limits the search results based on the temporal information. In an embodiment where the data is downloaded, the downloading of the data may trigger a search to be performed by the computer (or other processor system) that has downloaded the data. In a further embodiment, the geospatial location data is converted into a geographic place name such as a region or city to correlate with the supplemental data.

The medical professional is then able to crosscheck relevant reports and rare diseases with corresponding symptoms manifested in the individual by reviewing the information provided (730), for example, in an interface similar to that shown in FIGS. 5 and 6 by the computer or the device 110. The medical professional uses the provided information to assist in making a diagnosis based on the provided information.

An example of a known analytical method that would be suitable for the disclosed method is Multiple Correspondence Analysis (MCA). MCA is a data analysis technique for nominal or categorical data, used to detect and represent underlying structures in a data set. It does this by representing data as points in a low-dimensional Euclidean space. Associations between variables are uncovered by calculating the chi-square distance between different categories of the variables and between the individuals (or respondents). These associations are then represented graphically as “maps”.

FIG. 8 illustrates an example of an example interface in accordance with at least one embodiment of the present invention as discussed above with respect to FIG. 7. FIG. 8 depicts a graphical representation 800 of the health and geospatial location information of an individual stored by the device 110, 410. The graphical representation 800 provides a depiction of the temporal health and geospatial location information of the individual such that the correlated information can be used by a medical professional(s) to perform a more accurate diagnosis of the cause(s) for the illness and/or the disease inflicting the individual (or patient). By viewing the graphical representation 800, the medical professional(s) can quickly determine the recent travel of the individual and gain possible insight into the recent health of the individual. The illustrated biomedical readings can be representative readings such as an average for that biomedical parameter, a median of the readings at that geographic location for that biomedical parameter, and a range with the end points representing the lowest and the highest readings for that biomedical parameter for that geographic location.

The graphical representation 800 illustrated in FIG. 8 shows that the individual recently visited four locations including Location A, Location B, Location C, and Location D depicted as 880, 882, 884, and 886, respectively. One of ordinary skill in the art will appreciate based on this disclosure that the number of locations could be other than four as used in this example. In the illustrated interface for example purposes: Location A represents a location in Mexico; Location B represents San Francisco, Calif., US; Location C represents Prince Albert, Saskatchewan, Canada; and Location D represents Syracuse, N.Y., US. The geographic location may be set to provide the country, state, and city or the exact positional coordinates such as the latitude and the longitude. By clicking on links (or selection element) 870 associated with each of the respective locations the computer used by the medical professional or the device 110 provides the medical professional with additional information 872 related to that location. For example, the link at Location A—Mexico indicates that the patient, John Doe, visited Mexico on Apr. 1, 2010 for a period of two (2) days. The stored biomedical condition of the patient includes a temperature of 98 degrees Fahrenheit, a blood pressure of 122/81, and a pulse of 78. The health alerts reported by the World Health Organization (WHO) for this location on that date is shown to be H1N1 (Influenza A virus) and Dengue virus (DENV). The medical professional may also access additional stored health information and location alerts by accessing provided links 874. This information assists the medical professional in quickly and accurately performing clinical diagnosis of the individual. The medical professional may then report any diagnosed illnesses or diseases including location(s) to a central collection entity.

In a further embodiment, the system and method include the ability to limit the amount of medical information retained in memory. One way to accomplish this is to allow the individual to set a time limitation such that medical data older than a threshold is deleted. Examples of the threshold include, but are not limited to, a few days, one or more weeks, a month, three months, four months, six months, a year, multiple years, etc. A second way to accomplish this is to allow the individual to set a number of locations where only the most recent locations travelled to our retained, for example a number following in one of these ranges (including the end points): 1-50, 2-25, 1-10, 2-5, and 2-4. A third way to accomplish this is to use a hybrid approach between the two other ways using the way that would provide the smallest or the largest data set.

FIG. 9 illustrates an alternative interface for use with at least one embodiment of the present invention as depicted in FIG. 8. FIG. 9 depicts a table 900 of the tracked health and geospatial location information of an individual. The table 900 provides an alternative depiction of the temporal health and geographic location of the individual over a period of time. The table 900 allows the correlated information to be viewed and used by medical professions to perform a more accurate diagnosis of the cause(s) of the illness and/or the disease. By viewing the table 900, medical professionals can quickly compare the various recently visited locations and health of the patient by being able to view how the stored medical readings change over time (although a table is illustrated, this embodiment could illustrate line graphs, bar graphs or other pictorial representation of the underlying data). The table 900 provides various rows and columns of relevant information including, for example, the Location, Date, Duration, Health Parameters, Other Health Parameters, WHO Alerts, and Other Alerts. The table 900 is organized based on location, for illustration purposes the locations include Location A—Mexico, Location B—San Francisco, Location C—Saskatchewan, and Location D-New York from FIG. 8. Alternatively, the rows and columns could be switched with each other from that shown in FIG. 9 along with a different set of data being provided depending on the available data from the device 110, 410. As with the previous illustrated interface from FIG. 5, the same type of summaries could be used in the illustrated table.

The following scenario illustrates the usefulness of at least one embodiment using the data obtainable by the interfaces illustrated in FIGS. 8 and 9, the Mexican government or some other health organization, e.g., the World Health Organization (WHO), issue a health alert for Dengue virus and H1N1 in Mexico that were in effect on Apr. 1, 2010. Patient John Doe traveled to Mexico on Apr. 1, 2010 for two (2) days. The patient made stops in San Francisco, Calif. and Prince Albert, Saskatchewan before returning home to Syracuse, N.Y. on Apr. 7, 2010. The patient began to feel ill during his trip and visited a doctor in his hometown on Apr. 8, 2010. The doctor accesses the stored information of the patient and upon receiving the alerts realizes that the patient is exhibiting symptoms consistent with the alert for the H1N1 virus. The doctor is able to quickly and reliably diagnosis John Doe as having been exposed to the H1N1 virus while in Mexico and provide prognosis for recovery.

Another scenario illustrating the usefulness of at least one embodiment, John Doe visits Mexico on Apr. 1, 2010. There is a slight change in his blood pressure but he does not realize the change. After leaving Mexico John Doe travels to the United Kingdom where he gets very little sleep and feels a bit uneasy. John Doe then returns to the United States and his condition worsens. John Doe then visits his doctor. Upon reviewing the stored biomedical condition and geospatial location information related to John Doe, the doctor realizes that John Doe visited western Mexico on Apr. 1, 2010, that there was a slight increase in his blood pressure on that date and there was a health alert for Dengue virus in effect at that time. The system provides the doctor with the exact biomedical and location information related to John Doe including known diseases from regions to which he traveled. Utilizing this information, the doctor realizes that the onset on Dengue was the likely cause of the increase in blood pressure and avoids a misdiagnosis based on a lack of sleep and travel.

In a further embodiment, the device further includes a medical facility detector 1040 connected to the location module 112 as illustrated in FIG. 10. The medical facility detector 1040 determines when the device is present at a medical facility based on current geospatial data translated by the location module 112 and comparison of that data to available data such as that obtained from a wide area network or a medical facility database present in the memory 116. The medical facility detector 1040 than in at least one embodiment makes the medical and geospatial data stored on the device 110 available for viewing and/or transferring from the device 110. In a further embodiment, the medical facility detector 1040 prompts the individual for allowing access to the data based on the determination that the device 110 is present at a medical facility.

In a further embodiment, the medical facility detector 1040 receives a signal detected by the communications module 114 requesting access to the stored information and in response to the request provides access to the geospatial and medical data with or without additional information stored on the device 110. Examples of the source of the signal include attachment of an external device for retrieving information from the device 110, a wireless signal transmitted from the medical facility directed at the device 110, manual entry of a code or passcode by a medical professional on the device 110, starting of an application installed on the device 110, and the entry of a biometric identifier of the individual.

An example of the usefulness of at least one of the medical facility detector embodiments is an individual is traveling abroad, becomes ill and is taken to a local hospital. The individual becomes unconscious (or there is a language barrier) and therefore unable to provide the medical professionals with any information. The hospital has no means for quickly locating or contacting the family of the individual. The health of the individual is deteriorating quickly and time is of the essence—both to save his life and to determine if he poses a threat of contagion. The individual is carrying his mobile phone (or other device 110, 410) that is equipped with at least one of the embodiments of the present invention. The medical professionals access the mobile phone which provides a complete log of the recent travel and physiological condition of the individual. The correlated physiological condition and geospatial location information of the individual provide the medical professionals with enough information to determine that the individual has likely come in contact with an outbreak or “hot spot” identified that he recently visited. Using this information, the medical professionals are able to save the life of the individual. The medical professionals are also able to quarantine the individual to prevent a localized outbreak. The present invention not only greatly assisted in saving the life of the individual but also assisted in determining that a quarantine was necessary-thereby potentially saving the lives of countless others.
